Greg,
I have used Mobil 1 AFE twice now. Each time under different driving conditions. My driving used to be 25 miles average trips. No oil use great UOA.
This time lots of 3 miles trips and very little highway or full warmups. Although I do a 350 mile trips every other month or so to visit relatives.
Neither time have I used any oil or has the oil smelled of fuel.
My current fill is 8+ months old right now with 4400 miles on it. Now that my warranty is up, I plan on running it till late November, and do a UOA. It should be interesting to see how different driving environments show in the UOA.
I have also used PP early in the Tacoma's life, it was 5w-20 as 0w-20 used to be unobtaninum back in 2009, at least at a reasonable price. It performed pretty much as any oil I have used in the Tacoma. Great. Use either with confidence IMO.
